-19ln + -1lnx + 2lnx2 = lnx

Solving
-19ln + -1lnx + 2lnx2 = lnx

Solving for variable 'l'.

Move all terms containing l to the left, all other terms to the right.

Add '-1lnx' to each side of the equation.
-19ln + -1lnx + -1lnx + 2lnx2 = lnx + -1lnx

Combine like terms: -1lnx + -1lnx = -2lnx
-19ln + -2lnx + 2lnx2 = lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
-19ln + -2lnx + 2lnx2 = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-19 + -2x + 2x2) = 0

Subproblem 1

Set the factor 'ln' equal to zero and attempt to solve: Simplifying ln = 0 Solving ln = 0 Move all terms containing l to the left, all other terms to the right. Simplifying ln = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(-19 + -2x + 2x2)' equal to zero and attempt to solve: Simplifying -19 + -2x + 2x2 = 0 Solving -19 + -2x + 2x2 = 0 Move all terms containing l to the left, all other terms to the right. Add '19' to each side of the equation. -19 + -2x + 19 + 2x2 = 0 + 19 Reorder the terms: -19 + 19 + -2x + 2x2 = 0 + 19 Combine like terms: -19 + 19 = 0 0 + -2x + 2x2 = 0 + 19 -2x + 2x2 = 0 + 19 Combine like terms: 0 + 19 = 19 -2x + 2x2 = 19 Add '2x' to each side of the equation. -2x + 2x + 2x2 = 19 + 2x Combine like terms: -2x + 2x = 0 0 + 2x2 = 19 + 2x 2x2 = 19 + 2x Add '-2x2' to each side of the equation. 2x2 + -2x2 = 19 + 2x + -2x2 Combine like terms: 2x2 + -2x2 = 0 0 = 19 + 2x + -2x2 Simplifying 0 = 19 + 2x + -2x2 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
